Couple of notes....I often show people (in India particularly) the image and more often than not they do a bit of posing, a few laughs and you get the shots that you were dreaming of......and don't forget that you can make print while you are there; I like to make prints for people that I have met and who may not have many other possessions...it is a way of expressing respect rather than waving money around....and one more....keep your camera discreet, particularly if you are wandering around what might be a difficult area. And finally...don't forget that you can make stitched panoramas.
